Free Boundary Value Problems in Contact Mechanics

Gwinner, J (Universität der Bundeswehr München)
Wednesday 25 June 2014, 11:45-12:15

Seminar Room 1, Newton Institute


In this talk we report on recent progress in the solution of various non-smooth free boundary value problems that arise in contact mechanics, including unilateral contact with Tresca friction and non-monotone adhesion/delamination problems. We analyse these problems and employ for their numerical treatment optimization and regularization techniques combined with fi nite element discretisation. This presentation is based on the recent papers [1, 2] and the recent PhD Thesis [3] of N. Ovcharova.
